F&P Smartdrive GW603

[kleenasawisal]

Hi Team;

First of all a brief description of GW 603 machine failure. My wife was finishing a load of washing and the machine completed the final spin successfully. When she went to put in another load all the lights came up and thats where it stayed. After viewing your site, I gathered the necessary information to extract “code 49” (cold water valve). I had the valve tested in situ with water mains connected, valve disconnected from circuit wiring, but powered up via regulated 12 volt DC supply and machine started filling, proving that valve was operational. Could I please ask of any other probable causes apart from main circuit board malfunction. The voltage at the CWV connected to circuit was 7 volts??

Kind Regards GW

Re: GW 603-K

excuse my ignorance and poor punctuation what is a gw 603-k.

Re: GW 603-K

I think I’ve got it right. It’s a an 8 year old F&P 603 washing machine.

Cheers GW

Welcome to the Oz forum……… My learned colleague (and all the rest of the UK engineers) have never seen an F+P…….

Right – change the cold water valve. It is a proportional flow device – hitting it with 12v may open the valve fully, but it may be failing at lower voltages required to balance the flow against the hot inlet.

Hi Penguin45;

Thanks for your reply. I’ve just replaced both hot and cold valves, but now have a new bucket of worms to play with. I’ve checked and double checked with agents that they’ve supplied correct valves but voltages at both valves now at 16mv on normal start mode i.e. Power switch then Start switch. All operations are still nil. The diag code has changed now also, to 01101011 from right; code 107 ?
I’m not sure if it’s worth noting, that after pressing power switch, (but not start), on initial normal power up, 0 1 1 1 1 1 1 1 from right, (lamp bin code 64) continuously flashes. Thanks for all your help.

Kind Regards Graham

Hi Penguin45;

For the record, F&P = Fizz and Pop, unquote.

Re: F&P Smartdrive GW603

Cold valve should be 426143.
Hot valve should be 426142.

107 is a nasty – display board has detected that the motor controller has crashed, replacement required.

Always worth checking lid switch and Out of Balance switch – both suffer from dodgy wiring and corrosion.

Hi Penguin45;

Thanks. I really needed cheering up. Funny enough; My wife and I were standing beside the machine, (with the panel still open), discussing our next move, and there was a single, barely audible, “pop” from that area. I think, but I’m not certain, I saw a “tiny” flash from the right side of the contoller (standing in front of machine). I could not smell anything though. I disconnected the power supply and placed things together again but I thought I would try my luck just once more. Wallah, but still code 107. I ran through all the cycles and all seems OK? But in the motor trade there is a quote, “they go well just before they blow”. I’ll get a controller on standby. Thankyou very much for all your assistance.

Kind regards
Graham

Re: F&P Smartdrive GW603

You might just hit lucky – there is a circuit protection fuse on the board, which may have failed. If it has, get down underneath and have a look at the wiring to the pump and motor – if it’s chaffed, wet, rusty looking this is where the root of the problem lies.

Hi Penguin45;

Will have to leave machine now for a couple of days to attend prior arrangements, but will definitely contact you again once I’m back and had a peep at your recommendations. It’s all making logic now. All the same, I’ll wear the same underwear till fixed. Might speed things up????

Many, many Thanks

Hi Penguin45;

Thought I’d let you know how I got on with machine after a bit of fossiking. It would appear that the “pop & flash” I heard and thought I saw, came from the OOB switch which tested OK about 60 min prior. Must’ve disturbed it. It was corroded though as you mentioned earlier, and there was a wee bit of the dreaded electrical smell from it once it was removed, but machine still didn’t want to go after replacement. The circuit board protection fuse was OK but the connections and wiring at the motor were a bit………..you know, which you also suggested and I managed to correct those and get machine working again. Your diagnosis was 100{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} and Wifey is happy now. Do you ever tire of people singing your praises? Keep up the excellent work.

Kind regards
Graham
